BACKGROUND OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE PRESENTDISCLOSURE Technical Field

These non-limiting exemplary embodiment(s) relates to medical instrumenthandles and, more particularly, to an ergonomic multi-functional handleused to manipulate a medical instrument such as an electrosurgical,monopolar, laparoscopic instrument, for example, while reducing userfatigue.

Prior Art

Surgery is a learned skill requiring many years of training to developan understanding of medical procedures, disease processes and healingthat far exceed the basic medical principles. The surgeon must develophand-to-eye coordination and acquire skills utilizing a variety ofhighly specialized medical instruments. The medical instruments andtools are an extension of the surgeon's hand. The surgeon's ability toperform the medical procedures with instruments and tools designed tobenefit skill is paramount to the successful outcome for the patient. Toenhance the medical performance to better serve the patient meansdeveloping instrument handles which are responsive, sensitive andergonomically designed to benefit the natural motions of the human hand.

For example, laparoscopic instruments have been heavily developed foruse by surgeons during medical procedures since around 1980s. There aremany advantages of laparoscopic surgery compared with open procedure.These advantages include: reduced hemorrhaging which reduces needing ablood transfusion, smaller incision which reduces pain and shortens therecovery time of the patient, reduced scarring, reduced chances ofneeding pain medication, reduced hospital stays and quicker return toeveryday life, and reduced risk of contamination and infection.Disadvantages of a laparoscopic procedure include: limited range ofmotion in the medical site, poor depth perception by the surgeon, andoften laparoscopic tools are not perceived as moving in the samedirection as the surgeon's hands.

In a variety of medical devices used for a diversity of medical ornon-medical procedures, devices are designed with a dedicated handle orproximal end and a distal or actuation end. Typically medical devicehandles prescribe how they will be held in the hand by the layout oftheir handle shape or position of digit retaining portions. Ininstruments that contain loops, such as can be found in scissors typedevices or grasping type devices, the loops are used for opening andclosing the end effector, whether that is a scissors, grasper, clamp orsimilar device. In medical devices and more specifically minimallyinvasive or laparoscopic devices, a wide variety of angles of use can begenerated. Typically a digit-looped device locks the digits and handinto a single orientation that can only function comfortably across alimited range of angles. Both in angles distal or away from the user andoblique angles or angles acutely to the side of the user, devices withdigit loops move beyond their effective comfort range and promote handstress and fatigue. This stress and discomfort is the result of creatingunnatural hand postures. These hand postures can create severe wristadduction or flexion causing discomfort and a loss of strength orleverage to operate the device. In certain instruments such asinstruments used for minimally invasive or laparoscopic dissection, asurgeon may operate a looped device for long periods of time, across awide range of angles.

In other conventional instruments, the handle comprises two holes forinsertion of middle digit in one ring and digit in the other ring. Thesizes of these rings are often small and not optimized for all types ofhand sizes. This method in which the whole instrument is supported byonly a thumb and finger and in which case, the hand and wrists make avery awkward and unnatural angle with respect to the angle of use isoften very cumbersome to the surgeon and extended use of instrument inthis position causes severe fatigue and hand pain. This results inpainful situations during extended surgeries.

Accordingly, a need remains for an ergonomic medical instrument handleto overcome at least one of the above-noted shortcomings. Thenon-limiting exemplary embodiment(s) satisfies such a need by providingan ergonomic medical instrument handle that is convenient and easy touse, lightweight yet durable in design, versatile in its applications,and designed for easily and conveniently enabling a user to articulatehis/her digit while operating the medical instrument handle and therebyreduce fatigue and discomfort during extended medical procedures.

The linkage assembly 111 includes a first link lever 163 anda second link lever 169 pivotally coupled to opposite sides of thedistal end of the drive rod 113. Manipulation of the drive rod 113—viafirst trigger assembly 120—causes articulated of the first and secondlink levers 163, 169 about a common fulcrum axis 162 at the distal endof the drive rod 113. Such first and second link levers 163, 169 arealso pivotally coupled to first jaw 166 and second jaw 167, at joints164, 168, respectively. First and second jaws 166, 167 are pivotallycoupled to each other via a jaw pin 165. In this manner, when the distalend of the drive rod 113 is linearly urged—along distance 161—towardsthe first and second jaws 166, 167, the first and second link levers163, 169 are caused to pivot along first rotational directions, awayfrom a longitudinal axis 190 of the drive rod 113. Such pivotal movementurges apart the first and second jaws 166, 167 to an open position.Retraction of the drive rod 113—along distance 161—away from the jaw pin165 causes the first and second link levers 163, 169 to articulatetowards the longitudinal axis 190 of the drive rod 113 and therebyarticulate the first and second jaws 166, 167 towards a closed position.

Referring to FIG. 2, in a non-limiting exemplary embodiment, a partiallyexposed side elevational view illustrating the interrelationship betweenthe internal components of the multi-functional handle 100 shown in FIG.1, is disclosed. The first trigger assembly 120 operates the medicalinstrument 180 wherein the rectilinear drive rod 113 is housed withinthe shaft 103. A proximal end of the drive rod 113 is attached to adistal end of the actuation arm 129. Such a drive rod 113 may beconnected to the actuation arm 129 via a ball/socket joint 128, 142 orother fastener suitable for reciprocating the drive rod 113 along alinear travel path 161 defined parallel to the longitudinal axis 190 ofthe shaft 103 (as perhaps best shown in FIG. 14). FIGS. 6 and 8illustrate the drive rod ball joint 128 and actuation arm 129 ballsocket 142. Articulation of the first trigger assembly 120 iseffectuated by manual manipulation of the actuation arm 129 along thearcuate path illustrated by the arrow 112. Connection between theactuation arm 129 and drive rod 113 is spaced from the first pivot axis126 about which the first trigger assembly 120 pivots. A rotation knobjoint 105 is attached to the drive rod 113 at a distal location of thebody 150 so that the medical instrument 180 can be selectivelyarticulated via rotation of the actuation arm 129 at a proximal end ofthe body 150. Of course, alternately, the position of the actuation arm129 may be located at a distal end of body 150.

Referring to FIG. 2, in a non-limiting exemplary embodiment, anelectrical current may be supplied to the medical instrument 180 via ahigh-frequency (HF) connector plug 107 extending outwardly and away froma top of the body 150. A HF connector lead 106 is communicativelycoupled to the connector plug 107 and travels downward into a hollowcavity of the body 150 wherein it maintains electrical communicationwith the drive rod 113.

In a non-limiting exemplary embodiment, an energy source such as atissue-altering energy source may be communicatively coupled to thehandle 100. Exemplary tissue-altering energy sources may generate a heatsignal, acoustic signal, microwave signal, light signal, etc., aswell-understood by one of ordinary skill in the art. Eachtissue-altering energy source may include different components forinterfacing with the body 150 and/or the medical instrument 180. Thus,the HF connector plug 107 and lead 106 are not a necessity and aremerely provided as an illustrative example; not restrictive.

Referring to FIG. 3, in a non-limiting exemplary embodiment, an enlargedview of the second trigger assembly 130, taken in FIG. 2, is disclosed.As noted above, the second trigger assembly 130 permits selectivearticulation of a portion—actuation arm 129—of the first triggerassembly 120 along the arcuate path 112 for manipulating the medicalinstrument 180 (e.g., jaws). Of course, one skilled in the artunderstands a variety of medical instruments 180 may be manipulated bymovement of the first trigger assembly 120.

In a non-limiting exemplary embodiment, the second trigger assembly 130is employed to selectively lock the actuation arm 129 at alternatepositions, as desired. Thus, while the first trigger assembly 120permits operation of the medical instrument 180, the second triggerassembly 130 enables the user to lock the first trigger assembly 120 ata desired position thereby preventing further manipulation of themedical instrument 180.

In a non-limiting exemplary embodiment, as perhaps best shown in FIGS.3, 4 and 7, the second trigger assembly 130 preferably includes aratchet cam shaft 119 formed at the second pivot axis 127. A ratchettrigger 153 is statically coupled to the ratchet cam shaft 119 and isdisposed exterior of the body 150. The ratchet trigger 153 pivots aboutthe second pivot axis 127 thereby causing a ratchet cam shaft arm 116 toarticulate in a corresponding direction. For example, when the ratchettrigger 153 is rotated clockwise, the ratchet cam shaft arm 116 alsorotates clockwise; and visa-versa.

In a non-limiting exemplary embodiment, a ratchet cam shaft snap fit 117is formed at an end of the ratchet cam shaft arm 116 and locks to a snapfit anchor bracket 117 statically housed within the body 150. Forexample, the snap fit anchor bracket 117 may be friction locked,magnetically locked, or locked via other suitably ways, withoutdeparting from the true spirit and scope of the present disclosure. Aratchet pawl cam 121 is statically mated to the ratchet cam shaft 119and remains angled away from the ratchet cam shaft arm 116 such that itselectively displaces one end of a ratchet pawl 122. The ratchet pawl122 has an opposite end anchored to a ratchet pawl attachment boss 123located distally of the first pivot axis 126. In this manner,articulation of ratchet trigger 153 along a first rotational directioncauses ratchet pawl cam 121 to urge ratchet pawl 122 towards a ratchetarm 147 having a serrated surface. A proximal end of the ratchet pawl122 engages the ratchet arm 147 teeth 118 and the ratchet cam shaft snapfit 117 locks the ratchet trigger 153 at a locked position. Suchcooperation between the ratchet pawl 122, ratchet arm 147 and ratchetcam snap fit 117 prohibit premature or undesirable movement of theratchet trigger 153, thereby maintaining the medical instrument 180 at adesired orientation.

In a non-limiting exemplary embodiment, rotation of ratchet trigger 153in an opposite direction releases the ratchet cam snap fit 117 anddisengages the ratchet pawl 122 from the ratchet arm 147. Suchdisengagement permits the ratchet arm 147 to articulate in sync with theactuation arm 129 of the first trigger assembly 120 thereby permittingmanipulation of the medical instrument 180 as desired.

In a non-limiting exemplary embodiment, FIG. 4 illustrates an enlargedside elevational view of the multi-functional handle 100 forarticulation of the first trigger assembly 120 about the first pivotaxis 126. During manipulation of the medical instrument 180, the firsttrigger assembly 120 articulates about the first pivot axis 126 andalong a first arcuate path 112 while the ratchet trigger 153 is at alowered position (e.g., unlocked position). To prohibit manipulation ofthe medical instrument 180, the ratchet trigger 153 articulates along asecond arcuate travel path 124, and about a second pivot axis 127 offsetfrom the first pivot axis 126. When the ratchet trigger 153 isarticulated to a raised position (e.g., locked position), the actuationarm 129 is prohibited from rotating along the arcuate path 112. As notedherein above, raised/lowered positions maybe first/second positions andvisa-versa.

In a non-limiting exemplary embodiment, FIGS. 5 and 6 arecross-sectional views showing the interrelationship between the firsttrigger assembly 120, second trigger assembly 130 and third triggerassembly 140. FIG. 8 is an enlarged perspective view illustrating theinterrelationship between the third trigger assembly 140 and theactuation arm 129. FIG. 9 is an enlarged perspective view illustratingthe receiving aperture 146 of the primary digit-receiving member 131.With reference to FIGS. 5-6 and 8-9, the digit locking switch isreferred to as the third trigger assembly 140. Such a mechanism permitsselective movement of the primary digit-receiving member 131, which maybe a loop, for example. Of course, the primary digit-receiving member131 may be a variety of shapes and should not be construed as limited toonly a loop shape.

In a non-limiting exemplary embodiment, the third trigger assembly 140is operably coupled to the actuation arm 129 and primary digit-receivingmember 131 of the first trigger assembly 120. The third trigger assembly140 includes a switch 149 that is linearly reciprocated along a slot 145formed in the actuation arm 129. The switch 149 is partially insertedinto the actuation arm 129 and has a switch follower 133 staticallymated thereto. A switch snap fit arm 134 extends downwardly and distallyfrom the switch follower 133, traveling along a path 141 alignedsubstantially parallel to the reciprocating motion of the switch 149above. A switch snap fit 135 is formed at a distal end of switch arm134. Grooves 137, 138 are formed within an interior wall of theactuation arm 129. Such grooves 137, 138 are aligned substantiallyparallel to the linear path 141 wherein, when the switch snap fit 135 ispositioned in a proximal groove 137, the switch arm 134 is locked andprohibited from movement. When the switch snap fit 135 is slidablyinserted in the distal groove 138, a locking shaft 132 is displacedoutwardly from a receiving aperture 146 thereby permitting movement ofthe primary digit-receiving member 131. Although, the locking shaft 132has a hexagonal shape with a corresponding hexagonally shaped receivingaperture 146, any number of interlocking shapes may be used to prohibitmovement of primary digit-receiving member 131. The primarydigit-receiving member 131 is coupled to the actuation arm 129 via ajoint for maintaining the receiving aperture 146 within the actuationarm 129 during movement of the primary digit-receiving member 131;prevents primary digit-receiving member 131 from disengaging the lockingshaft 132.

In a non-limiting exemplary embodiment, with reference to FIGS. 4 and 7,an enlarged perspective view illustrating articulation of the ratchetarm 153 about the second pivot axis 127 is disclosed. Also, a referenceline 191 is shown passing through the secondary digit-receiving members155, 156 located along a medial portion of the body 150. Suchillustration in FIG. 7 shows an optional movement of the medicalinstrument 180 along approximately a 100 degree arcuate path. See alsoFIGS. 21 and 21A for further illustration of the medical instrument 180movement relative to the medial portion of the body 150.

What is claimed as new and what is desired to secure by Letters Patent of the United States is:
 1. A multi-functional handle for manipulating operation of a medical instrument, said multi-functional handle comprising: a body having a centrally-registered longitudinal plane and capable of being gripped; a first trigger assembly coupled to said body and comprising an actuation arm, and a primary digit-receiving member in communication with said actuation arm; wherein said primary digit-receiving member is selectively displaced between alternate orientations relative to a position of said body and relative to a position of said actuation arm, respectively; and a second trigger assembly operatively coupled to said first trigger assembly in such a manner that said actuation arm is selectively locked at alternate positions generally coplanar with the centrally-registered longitudinal plane of said body.
 2. The multi-functional handle of claim 1, wherein said first trigger assembly is pivotal about a first pivot axis, wherein said second trigger assembly is pivotal about a second pivot axis, wherein each of said first and second pivot axes are offset and traverse the centrally-registered longitudinal plane of said body.
 3. The multi-functional handle of claim 2, wherein said primary digit-receiving member is simultaneously displaced relative to said actuation arm while said first trigger assembly is articulated about said first pivot axis.
 4. The multi-functional handle of claim 1, wherein said primary digit-receiving member is adjustably positioned about a proximal end of said actuation arm.
 5. The multi-functional handle of claim 1, wherein said actuation arm is displaced along a first path generally coplanar with the centrally-registered longitudinal plane of said body.
 6. The multi-functional handle of claim 1, wherein said primary digit-receiving member is a loop capable of receiving a digit of the user while the user grasps said body.
 7. The multi-functional handle of claim 1, wherein said primary digit-receiving member is an incomplete loop capable of receiving a digit of the user while the user grasps said body.
 8. The multi-functional handle of claim 1, wherein said primary digit-receiving member has a linear shape capable of supporting a digit of the user while the user grasps said body and said actuation arm is articulated along a first path.
 9. The multi-functional handle of claim 1, wherein said primary digit-receiving member is registered parallel to the centrally-registered longitudinal plane of said body.
 10. The multi-functional handle of claim 1, wherein said primary digit-receiving member is registered oblique to the centrally-registered longitudinal plane of said body.
 11. The multi-functional handle of claim 1, wherein said primary digit-receiving member is registered orthogonal to the centrally-registered longitudinal plane of said body.
 12. A multi-functional handle for manipulating operation of a medical instrument, said multi-functional handle comprising: a body having a centrally-registered longitudinal plane and capable of being gripped by a hand of a user; a first trigger assembly in communication with said body and comprising an actuation arm, and a primary digit-receiving member in communication with said actuation arm, said actuation arm being capable of actuating a medical instrument independently from movement of said primary digit-receiving member; wherein said primary digit-receiving member is selectively displaced between alternate orientations relative to a position of said body and relative to a position of said actuation arm, respectively; and a second trigger assembly operatively coupled to said first trigger assembly in such a manner that said actuation arm is selectively displaced at alternate positions generally coplanar with the centrally-registered longitudinal plane of said body; wherein said actuation arm includes a ratchet arm statically connected thereto.
 13. The multi-functional handle of claim 12, wherein said ratchet arm is monolithically formed with said actuation arm.
 14. The multi-functional handle of claim 12, wherein said ratchet arm is coplanar with said centrally-registered longitudinal plane of said body.
 15. The multi-functional handle of claim 12, wherein said ratchet arm is integrally mated to said actuation arm.
 16. The multi-functional handle of claim 12, wherein said ratchet arm remains fixedly coupled to said actuation arm during articulation of said first trigger assembly.
 17. The multi-functional handle of claim 12, wherein articulation of said second trigger assembly from a first position to a second position permits articulation of said first trigger assembly along a first path; wherein articulation of said second trigger assembly from said second position to said first position prohibits articulation of said first trigger assembly along said first path.
 18. The multi-functional handle of claim 17, wherein said ratchet arm is permitted from moving in sync with said actuation arm when said second trigger assembly is displaced to said first position.
 19. The multi-functional handle of claim 12, wherein said second trigger assembly is selectively engaged to said actuation arm.
 20. The multi-functional handle of claim 12, wherein said first trigger assembly is continuously engaged to said actuation arm.
